Begin by discussing the Fibonacci sequence, which was first observed by the Italian mathematician Leonardo Fibonacci in 1202. This is also called ‘expanding symmetry’ or ‘evolving symmetry’. Fractals have self-similarity on all levels. Visually, fractals are a never-ending pattern that can be zoomed in on infinitely. Discover examples of symmetry, fractals and spirals, Fibonacci patterns and tessellations. The Fibonacci Sequence in Nature Copies of the Creating the Fibonacci Spiral handout Computers with Internet access (optional but very helpful) Procedures 1. Fractals are a natural phenomenon or mathematical set that exhibits a repeating pattern that displays at every scale.1. Lindenmayer system fractals can model different patterns of tree growth by varying a small number of parameters including branching angle, distance between nodes or branch points ( internode length), and number of branches per branch point.įractal-like patterns occur widely in nature, in phenomena as diverse as clouds, river networks, geologic fault lines, mountains, coastlines, animal coloration, snow flakes, crystals, blood vessel branching, and ocean waves. Nature is full of several types of patterns that are naturally occurring, non-random organized sequences. clouds, coastlines, trees etc.) I understood. Fern-like growth patterns occur in plants and in animals including bryozoa, corals, hydrozoa like the air fern, Sertularia argentea, and in non-living things, notably electrical discharges. Fibonacci is literally everywhere - in petals, sunflower seeds, branches etc. No, it is a sequence of integer numbers starting from 0 (optional), 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, each being the sum of the two preceding Fibonacci numbers. For example, the leaves of ferns and umbellifers (Apiaceae) are only self-similar (pinnate) to 2, 3 or 4 levels. Fractal geometry is often found in the jagged edges of natureferns, clouds and mountains, for examplebut the artificial fractal images that most resemble these forms are produced by trial. Infinite iteration is not possible in nature so all ‘fractal’ patterns are only approximate. Romanesco broccoli, showing self-similar form approximating a natural fractalįractals are infinitely self-similar, iterated mathematical constructs having fractal dimension.
